Glass sculpture, vessel format • Dale Chihuly; Studio of Dale Chihuly

Style & Movement
Contemporary Studio Glass Movement
Medium & Technique
Hand-blown glass; combination of 'Mezza Filigrana' (canework) for the striped interior and 'Macchia' (spotted or layered) technique for the opaque scarlet exterior shell.
Creation Period
Late 20th to early 21st century (likely 1981-2010)
Dimensions & Format
Estimated 8-12 inches (H) x 15-20 inches (W); horizontal organic format
Subject Description
An organic, biomorphic vessel resembling a sea shell or flower blossom. The piece features a vibrant scarlet red exterior juxtaposed with a complex interior of nested green and gold linear bands. The form is characterized by undulating, gravity-driven 'lips' that create a sense of fluid movement.
Condition & Value Assessment
Condition Assessment
Very Good; the glass appears vibrant with no visible fractures or significant surface scratching from this angle.
Estimated Market Value
$15,000 - $25,000 USD
Auction Estimate
$12,000 - $18,000 USD
Provenance History
Likely acquired via a fine art gallery or high-end glass auction; pieces from the Macchia series are widely collected by major institutions and private estates.
Art Historical Significance
The Macchia series (started in 1981) represents Chihuly's desire to use all 300 colors available in the glass factory. It is a seminal series in the Studio Glass Movement, shifting glass from functional craft to large-scale fine art sculpture.
Notable Features
The contrast between the 'Mezza Filigrana' internal canes and the 'Macchia' exterior is a hallmark of Chihuly’s technical mastery in layering different Venetian glassblowing traditions.
Condition Issues
None visible; potential for internal stress fractures or minor shelf wear on the base (pontil mark) which are common in heavy glass sculptures.
Conservation Recommendations
Keep in a temperature-controlled environment; clean with soft microfiber and distilled water; avoid direct high-heat spotlights which can cause thermal expansion stress.
